Any word on when the V6 Reo might be out?

The only improvement they could make at this point would be going to the new material that OR is using. The V5 is rock solid.

Cool, my Reos v5 will retain good value longer

Reo has reverse pigtails to Cabrinha and most other brands. Ocean Rodeo use to have same as Reo but changed this year to be what is becoming the industry standard used by Cabrinha, North etc.

Ozone decided to stagger the release of the Enduro and Reo to alternate years, this year is the Enduro V3, next year will be Reo V6 and I'm sure they will starting work on it real soon.
What is exciting to see though are the changes on the Enduro V3, which is the first model to carry the new Teijin triple ripstop canopy that weight no more than D2 and the new Teijin made triple ripstop LE material (dacron), and a very well designed high flow, no hose kink one pump system. The 10m demo I just received in Lennox weighs 2.7kgs which is very light compared to most kites made from Teijin materials or polyester/dacron kites.

Can you not just swap them over or the pigtail lengths different?

Yes, you can just swap steering lines to power lines pigtails and vice versa. The pigtails are equal length. That is what I do on my Enduros. Takes about 2 minutes to complete :)
